I just got my CCNA a few months back and am working on the CCNP (hoping to be ready to take the BSCI in the next couple weeks). While I agree some of the multiple choice is purely memorization and doesn't prove much, the test is still valid. There is enough information covered throughout the CCNA to where I had to study the books and do the labs to the point where I was pretty proficient at it and knew exactly what I was doing with everything. While the certification itself may not carry much weight (or maybe it does), getting to that point was a huge learning experience. I'm more interested in learning and becoming skillful at new things than worrying about what a certification says about me. In a job interview I can demonstrate those skills rather than wave a piece of paper around, but that paper helps give me the opportunity to do that.
The network admin probably disabled cdp on everything for security reasons. Also if the device in question is not a cisco then it wouldn't show up anyhow. I believe the cisco discovery protocol is proprietary.
If it's meant to help kids connect their Wii's to the internet it likely has an auto-pairing feature that will be introduced with an upcoming firmware patch. So in Wii system menu they just say 'Use Nintendo Wii Router' and it finds the closest one, generates a random encryption key, and automatically pairs with it rather than the current configuration required on both ends. The router itself may even only accept client connections from MAC addresses that are assigned to the Wii.
The switch on the back that changes it from router to bridge confirms that thing thing is most likely not manually configurable and will do all the encryption/pairing automatically.
I am confused though why this was designed as a router and not simply a Wii access point? Surely most home users with broadband already own some form of router/switch they could just plug it right into, and the fact it has no built in switch seems to go along with that model.
This doesn't look interesting to me but all the kids/moms/non-techy people out there who don't know how to configure their home Linksys or DLinks will find something like this useful.
All I said was it doesn't make sense to sue someone who makes something that can be abused and used for something it wasn't intended for (eg microSD cards). The R4 was not designed for piracy, it is a developer tool plain and simple. It is simple common sense.
Perhaps Nintendo thinks it can go around and sue anyone for anything because they lost that ridiculous law suit over joysticks?
Don't lie to yourself, nobody's clamoring to buy this to play any of those games. This is designed for piracy. I guarantee >95% use it exclusively for getting non-homebrew games.
I suppose they should also sue anyone who makes the microSD cards since they are the medium stores any copyright code the R4 may use. Now let's expand that to include Sony, Maxwell, and all the other companies that make blank CD-R's and DVD-R's because they can be used to copy copyrighted material.
This is utterly ridiculous. The R4 is a development tool, if it can or can not run copyrighted code is irrelevant. I've had one of these things for a while and I have to say they are pretty awesome. (I'm a developer.)
These companies need to get over themselves and focus on making quality products consumers want to buy and stop blaming their shortcomings on piracy that only a tiny fraction of their potential customer base even abuse.
The Wii controller can tell when you're doing a bowling type motion, but it cannot tell that your controller is 3.231 meters away from the sensorbar. You need the latter to get true 1:1.
Actually you can estimate how far away from the screen you are. This is done by using the two IR dots on the sensor bar. The sensor bar is a fixed length, so at a certain position the camera can look at the two dots and see how far away they are, then compare it to how far away it should be at X meters. As the dots get closer together the wiimote is getting further away, and based on how close they are you can estimate how far away it is at that point.
This obviously would not work if you didn't have a sensor bar, and I do not believe it can work without it even if they do add a gyroscope. Really the only way to track 3d position (IMO, and I'm not an expert) is to have some external beacon that can be used as an origin. I believe the 1:1 motion they are referring to is absolute orientation which is impossible with just one accelerometer. The wiimote can currently estimate roll or pitch (and even yaw to within ~20-25 degrees using the IR dots), but once you begin to combine then (ie, roll + pitch) the angles become distorted because you do not know where gravity really is. So with a single 3-axis accelerometer gravity is both responsible for your calculations but is is messing them up when you try to get too in depth.
He was referring to the distance of the IR dots on the sensor bar. If they are closer together (ie, the bar is shorter) then the cursor would be more sensitive. To prove this just move further away from the TV, which does the same thing as reducing the side of the bar. The GP is correct in that an adjustable telescopic sensor bar would be a great add-on, and should have been shipped with the Wii from the start. There are a couple on amazon (which got bad reviews for its weakness in other areas), or you can make one yourself. I've seen one made out of legos that looks pretty cool.
Gyroscope? Second accelerometer at a different orientation than the one in the wiimote? The article doesn't say anything except that it apparently exists.
As a SourceForge user in Beijing, I can confirm this first-hand. I also tried traceroute to sourceforge.net, only to find the connection being dropped at a Beijing ISP's gateway router.
Sounds like their router (or firewall) has a null route (or some equivalent device) for SF's IP addresses rather than where they are normally supposed to be sent to, ie the next closest router. DNS is just for IPhostname conversions, which would be done before the traceroute even starts (if he did traceroute sf.net).
Try telling this to a large company that is current running Windows Server 2003 servers with hundreds, if not thousands of, Windows XP clients. Yeah I'm sure it would be worth it for them to completely up and move their infrastructure to OSS.
I use Linux at home. It's great for home and does exactly what I want and need it to do. We run Windows at work. It's great for work and does (mostly) what we want and need it to do. Clients integrate nicely with the Active Directory system, with the Exchange server, we get a decent Office suite, and most importantly we get centralized support. I can't say from experience how well MS support actually is, but I can't imagine FOSS giving much phone support if my NFS server goes down for some reason.
What about all the various backup products, such as tape backups and seamless server redundancy? Are there alternatives for this for Linux? What assurances does a large company who absolutely can not afford significant downtime have that the software is well supported by professionals on call and that bugs are constantly being fixed?
This isn't all just Microsoft, this is the entire MS platform. There are thousands of tools that are necessary for full production environments that were designed specifically for Windows. Companies need this stuff.
Though I may not like Microsoft much, I do admit they have a nice overall package for easily setting up and maintaining a production network. They have lots of tools that fit together easily. While there may be Linux alternatives for some of this stuff, if you go to a business and tell them that they will likely say, "and what happens if it goes down?"
This d-link review really puts it into perspective:
All the High end networking stuff you need! insane speed on both wired and lan. Youll probably be alittle in shock at this thing when you ralize that the bottleneck is on your modem... this thing can handle a lot of load and when it comes down to it you just might want to tell your ISP to speed you up!
Damn straight. It's got gigabit WAN.. G I G A B I T.. booyah. None of this slow ass 100Mbit crap for me thanks.
Now to leverage the speed of the NIC's onboard processor and the Xtreme N Gaming Router (with LED display!) you need some serious ultra premium link cable to maximize the bandwidth that is typical with high speeds this nature. We finally a cable that can do that.
This is an interesting project, if not a little nerdy. Topics like this seem to pop up once in a while here and it's starting to become more interesting each time I see one.
I did a little bit of basic (very basic) circuit design in school, but I've since forgotten everything and no longer have any books or notes. It would be fun to play around with stuff like this, but since I know virtually nothing about circuitry I'm really not sure where to start or how committed I'd have to be to tinker with projects of this scale.
Is this a hobby that requires an immense amount of time or could I just devote a couple hours a week to it and be able to do some basic stuff within a month or two? Can anyone recommend any books? Also, where would I get some of the beginner testing equipment, such as the breadboard and different kinds of chips, from?
if you assumed reiser's innocence, take a good har dlook in the mirror
Everyone should be assumed innocent until it is proven beyond a reasonable doubt that they are guilty. I don't need to look in the mirror to know that...
You'd have to put it on some device in between your modem and your network, otherwise you are only counting usage per machine and not per connection. Maybe some application on your router? Cisco has one called NetFlow; it would be nice to have something like that but for cheaper LinkSys devices, maybe some 3rd party firmware? DD-WRT has a nice looking moving usage graph, but afaik it doesn't do any history or per-port/per-mac address stats so you wouldn't be able to tell where on your network the rouge bandwidth hog is located.
The board is very sensitive and you don't need to lean much for the sensors to pick up a significant weight distribution change (there are four weight sensors, one on each corner). Anyone who hurts themselves on this thing is an idiot. The only excuse for hurting yourself with this thing would be if you were already hammered and just happened to already be falling over.
It's not a no-brainer because the balance board did not ship with the Wii. There are a lot more people that own just a Wii than there are that own both a Wii and the balance board peripheral device. By targeting just those who have a board they are limiting their potential customer base. If the board is just an option, offering a new experience but not drastically limiting the gameplay without it, then yes it would be a no-brainer.
What happened to the other game they were working on? The one that was said to be not entirely within their FPS genre -- I think it was called Rage? I don't remember id ever working on (at least not publicly announced) concurrent projects. Will we ever see this project or has it merged into Doom 4?
Yes, but there appears to be a trend that is moving away from lower level coding, where there is a need to be careful and you do need to take your time to find an eliminate bugs; elegant and efficient programming does not seem to be as great a concern as I think it should be. If computers have more RAM then let garbage collection take care of your memory management woes; if CPU's are getting faster then maybe we should use inherently slower, but more programmer friendly, techniques to deal with threading.
In business applications this approach works fine -- you get a quick solution that fixes your immediate problem. When it comes time to deploying a solution to end-users I strongly disagree with taking the easy path -- just because your end-user has more system resources than they did 3 years ago doesn't mean you can write a slower application. Threads work. Handling memory yourself works. Maybe there are better techniques that will emerge, but those techniques should not, and can not, degrade the performance we can achieve with current methods.
Agreed. If they think this is a bad idea does that mean they don't do it in house? If so, that is very surprising and I would expect any and all anti-virus companies to not only test their software but also actively try to break it. Otherwise their stance must be 'wait and see' and fix bugs as the come up. Unfortunately these bugs can have severe consequences with this type of software, which can (and probably will) lead to their customers losing millions, possibly more, in damages from viruses that slip though holes in detection because the company was too lazy to try to stay one step ahead.
For any anti-virus company that thinks this is a bad idea, I question how much they really care about their customers.
Are you suggesting Microsoft is pulling a Coca-Cola? Change their formula to suck then bring back the original and make billions? I guess it could work...
ever reported a quarterly profit. The two companies have always lost money. If they don't merge it is likely at least one of them is going to go bankrupt and the other would probably just take over some of their previous customers anyway. I don't see why everyone is bitching, them merging is a good for both them and their customers.
Also I don't know this for sure, but since Sirius would be the buyer here wouldn't they make sure their combined network is compatible with both existing Sirius and XM hardware? Changing that would only piss their customers off, so those of you who already have Sirius or XM shouldn't need to buy new stuff.
